@TK3600 I think you mean you're using fighter jet generation to describe the
corresponding timeline of the specific CCA platform being introduced to service. Rather than the capability since that is more loosely defined.
We should remember that CCAs are not tied to any generation of fighter or AEWC. A J-16 can be paired with multiple types of CCAs from low tier to high tier. These new CCAs are simply showing that the Chinese CCAs are considerably larger than the American CCAs being developed and tested. Not to mention, these Chinese CCAs are either in service already or close to reaching service. Smart money I think would say these high tier CCAs have been tested with the PLAAF to run evaluation long ago enough to show them publicly. The next generation of platforms are in the works.
We've all watched PLA and the patterns for the last decade plus and charted out the patterns of disclosure for long enough to know. Just fill in the blanks backwards and notice the patterns. These CCAs they're about to show have been flying with PLAAF for years. They are PLA units. They have been testing them for a while and running new doctrines with these networked platforms to develop overaching strategy, tactics and training. GJ-11 diverted from this pattern somewhat due to there being such a volume of promising low to high tier UAV/CCA and drone swarm tech that was being tested in the 2010s. Whatever happened to Dark Sword?
